. This invention relates to improvements in pin setting devices adapted for use in connection with the game of bowling or the like.

The prime objectief this invention is to 5 provide animproved means for quickly and eflieiently returninglthe pin to its `housing after the pin'has beenV reieased from magnetic contact and connection with the alley of Y the-game. y ,4 .Y j y 10 A further object of this invention is to provide a housing for the pin on its release from the alley having therein resilient means mounted on a spindle for actuating a pulley having wound thereon a cable of wire or otherwise for raising the pin.

Other objects of this invention will appear from the following detailed description of the device and as disclosed in the single sheet of drawings which is herewith made a part of this application.

In the drawings:

Figure l illustrates a vertical elevational view of the housing and the pin spaced from each other under tension, the pin being held on the alley by magnetic attraction and against the potential energy of a spring wound on a spindle within the housing. Y

Figure 2 illustrates a vertical sectional view of the housing, disclosing the pin in raised position therein.

Figure 3 represent-s a sectional view of the Figure 2 taken'along line 3-8.

Figure 1i represents a sectional View of the upper portion of the housing, disclosing the the spring being disclosed under tension as it would be in case of the pin being in position are quite largel and heavy. The object, therefore, of this invention is to provide a more positive means for returning the pins to the housing than that now in common use, and as internally threaded portion 2 for the pur- 5 suitable device.l A cable member `7 made of spindle for supporting the pulley and spring,

games of bowling, where the pins and balls ferred that Number 1 designate the main body portion of the housing which may be made of any suitable material such as metal, and provided at its lower or open end with an pose of receiving in cooperative relationship a clamping element 3 adapted to clamp the housing 1` in firm and fixed relationship to a plate member 4 which by somemeans not shown is adapted to be lowered or raised as may be desired in order to set the pin 5 in playing position upon the alley 6, the pin 5 being detachably held in position on the alley 6 by means of magnetic attraction or other 4through the length ofthe pin and anchoring it in position at the lower end in the old and `common manner. l y

As above described, one end of the cable 7 is fastened securely to the eye 8 as disclosed in Figures 2 and 3, the other end of the cable 7 99 lis secured by some suitable means to a3 pulley member 11, which is mounted and keyed upon a spindle element 12-rotatively supported in theupper part of the housing 1 as at 13 `and 14. "A tension leaf spring 15 is also mounted n upon the spindle 12 in such a manner thatwhen the pin 5 is in lowered position, as disclosed in `Figure 1, the spring 15 will be wound under tension around the spindle 12,

l as clearly disclosed in Figure 4. As ameans W5 for accomplishing the desired result, one end `of the leaf spring 15 may be mounted on a pin member 16 extending from the housing 1, the other-end of the leaf spring 15 being securely fastenedto the spindle 12 as at 17 in such a-manner that when the pin is in raised position, as shown in Figure 2 the leaf spring 15"will he unwound and comparatively` loose: around the spindle. one modification of the invention, it is pre- Itis apparent fromlthe above description that when the pin 5 isl released from Contact with the alley 6 it will snap upward into position within the housing l, and in order to eliminate the possibility of the head of the pin striking the pulley 11, and other mecha-` iiismwithin the housing l, it is preferred that a bumper 1 8 be provided made of anysuitable material "such as rubber, havingjan opening 19 therein through which the cable 7 may i), loosely and slidably extend. As a further aid in relieving the shock of compaet between the pin and housing, bumper springs 2O are or otherwise.'

provided, arranged in suoli a manner that the bumper 18 will bel attached thereto, one end of the bumper springs QUbeing' held in fixed? relationship to the housing l by means of inwardlyle'xteiiding'grooved portions 2l of the housing.' f

y This invention provides a very efhcient means for'returning the pins to the housing after being released from Contact with the alley by means'fof thestriking of the balls The prime 'advantage over other means is that thel need ofl a long spring :.1 is entirely eliminated, a cable of wire or othi erwise taking the place yof the` ordinary kspring; rIhe power or'force`necessary` for returning` the pin to the housing is obtained tative'lymounted within the housing, a pulley i having a leaf tension spring ixed on the spindle, a cable attached to the'pin and pulley 'for winding thereon when the spring is under tension and the pin released rfrom the alley,

a buffer positioned within the housing be-V tween the pin and spindle comprising aV main body member and a pluralityv of auxiliary buffer' springs.v j A Y In testimonyI whereof I 'affix myv signature.

' It4 will be vunderstood that manyl elianges and modifications may be Vmade, in the form of the` improvement ofthe invention, within the scope ofthe following Claims', without i f departing from'thespirit of the invention.
